Have you been reading about the huge security holes in Facebook quiz applications? I learned about those here on HN.

I'm increasingly annoyed by Facebook's flailing about with its business model, and also annoyed by the large number of network errors I've seen on it in the last forty-eight hours.
I don't see Facebook's going public as a bad thing, as long as it's not a mandatory change. Their feed system certainly works publicly: It's much more involved than Twitter, and it supports a lot of things people would use other sites for. I use it instead of Flickr for public photos. I'm thinking of switching my Vimeo videos over so I can close my Vimeo account and run most of my online activities from one place. I like writing private friend-based notes, but if I didn't then Facebook notes would make for an attractively minimal solution.
Facebook's been gradually simplifying itself. I don't see how it's dumbing down when they've been adding features rather than taking them away. The new live feed is incredible, for instance.
Instead they're dumbing everything down to become what exactly, a lamer Twitter than Twitter itself?
